IMPROVEMENT IN MlLK-COOL ERS.

Specification forming part of Letters Patent No. 146,084., datedDecember 30, 1873; application filed June 24, 1873.

To all whom it may concern:

Be it known that I, RoswELL P. MAIN, of Canton, in the county of St.Lawrence and in the State of New York, have invented certain new anduseful Improvements in Milk-Coolers; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangementof a milk-cooler, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and, operation, referring to the annexed drawing, in which-Figure 1 is a perspective view of my entire milk-cooler, and Fig. 2 is asimilar view of one end of the cooling apparatus.

A represents a milk-pan, of any suitable construction and of any desiredsize and shape. 0n the bottom of this pan A is placed the coolin gapparatus, which consists of fourflat tubes, B B and B B, extending theentire length of the pan. Above the pan, at one end, is an elevatedtrough, 0, provided, near each end, witha spout or outlet-tube, a, whichleads into tapering tubes D D. These tubes are screwed one into each ofthe side tubes B at one end, water flowing ina constant stream into thetrough O, and, through the spouts a and tubes D D, into the flat sidetubes B B the entire length of the same; then, through connections I) bat the other ends of the same, into the two fiat center tubes B B. Thewater then flows back through said center tubes B B into a connection,d, between them, from which it passes, through a curved tube, E, overthe edge of the pan A into a trough, G, located under the bottom edge ofthe pan. At one end of this trough is a tube, H, with an elbow-pipe,

I, capable of being turnedin either direction,

so as to convey the waterwhich has passed through the cooling apparatusto any place i where desired. The milkin the pan A is emptied, throughthe same trough and pipe, into a vessel placed for its reception by aspout, h, in

the bottom of the pan.

The cooling apparatus can readily be removed from the pan for cleaningor other purposes, when desired.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- The combination, with amilk-pan, A, of the flat tubes B B and B B,with connections 1 d, troughO, with spouts a a, inlet tubes D D,-

outlet-tube E, and trough G with adjustable elbow-pipe I, substantiallyas and for the pur-= poses herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this21st day of May, 1573.
